Fig. IV is an enlarged detail sectional view taken on a line corre sponding to line H of Fig. II, showing what .I denominate the anti-kick switch and connections. Fig. V is an enlarged detail transverse sectional view taken on a line corresponding tojline 5.5 ofFig. II, showing engine as made use of in conjunction with a Mea magneto. Fig.-VII- is av detaileplan view of the Mea magneto, as illustrated in Fig.. VI. :Fig. VIII is-an enlarged detail longitudinal sectional View :through the handle socket taken on a line corresponding to line. 88 of Fig. IX. Fig. IX is an enlarged detail transverse sectional view taken on a line corresponding to line 99 of Fig. VIII.

In the drawing, all of the sectional views are taken looking in the direction of the little arrows at the ends of the section lines,

and similar parts are referred to by similar numerals throughout the several views.

Considering the numbered parts of the drawing, the, engine 1, of the four cylinder type each with a spark plug, is provided with a crank shaft 2 on which is a suitable crank 3 for'starting the same. Equivalent starting means may be provided. A handle keeper socketl is provided for; the handle of the crank 8, in, which are disposed switches that j are automatically operated by applying or removing the handle keeper socket from the crank handle. The keeper handle socket is secured by. stra 5 to a convenient part of the machine. he socket is I provided with a longitudinally disposed spring 6 against which the handle acts when the keeper socket is being put on or off the crank handle,see particularly Fig. VIII,

to control the switches carried thereby to control the circuits associated therewith.

. The insulated push pin 7 issecured to the end of the spring member 8 by screw 8', which urges the same inwardly against the spring 6. An outer spring member 9 of the switch is disposed to overlap the end of the spring 8 so that when the push pin? is pushed out by the action of the longitudinal spring 6 this switch isclosed with arubbing contact. The relation ofthese parts clearly appears in Fig. III. This is theanti-start switch. The members of thisswitch are connected to the conductors l6 and17, the

relations of which the circuit"will be hereafter definitely pointed out;

-The structure of the anti-kick switch ap-- pears clearly in Fig. The insulated push pin-10 is secured to the" flexible spring member 11 by the'screw' 11;. constituting one memberof the switch. This presses against a the: opposite yielding member 12,- and these close and complete"thecircuit in" the conductor,33 33,'as'very clearly appears when the socket is Y on the handle. The anti-bat- 'tery switch isoppo'si'te in'actiontothis, and

" When-the clutchor gear shiftlever-22 is in the neutral position, as indicated in, Fig: I,

the connected parts become a part of the battery circuit leading to the dashswitchand" coil 24. The battery=25 is connected at one side'to the conductor17 and atthe opposite side is connected'by theconductor 26 to the primary ofthe dash-coil. The-conductor 27,. leads from the time!- 28 to the dash switch:

and coil. The conductor 29 leads from the dash switch .and=-coil to, the timerand constitutes the usual timeriscircuit *connection' and is associated ln'theusual' way for insur a;

In the Mea magneto, the armature carries a low tention primary and a high tension secondary winding connected in series. The

7 low tension winding is ordinarilyshort circuited b'y-a breaker which opens at certain points of 'each revolution, with the result that a high voltage, is generated across the high tension winding at the moment of the spark gapgin, thecylinder to which it is connected; ltwill therefore be seen that whenhthe lowtension winding is short circuited that .the magneto will not operate to producethe spark. I, therefore, have adapt; ed-.my devices so that when;-thehandle keeper socket removed fromthe handle and thetimer set at an earlyspark, there willbe 2t;-{Slfi0't circuit formed so that the magneto will be inoperative to produce a spark. To accomplish this, I have added 'break,and a spark produced across the the contact 42 'on'the insulation 43 and'the contact strip 44; to, coact therewith for, effecting, the short circuit when the magneto is set attheiearly'sparkwhen the keeperis .oihthe handle.

course, only adapted for usewhere therelare the systems I haveillustrated make useofa jump spark for the ignition, but it iszvery clear that the circuits and switches which .I
